Product description
Its electrical characteristic assigns the Bosch Rexroth MDD065B-N-040-N2M-095GA0 to the 4000-min⁻¹ version of the MDD range. With natural convection, continuous standstill torque is 1.5 Nm and the associated continuous current is 3.5 A. The theoretical maximum torque is 4.4 Nm, while peak current is 15.9 A. Further values are a torque constant of 0.43 Nm/A, winding resistance of 5.22 Ohm and winding inductance of 7.4 mH. The rotor has a moment of inertia of 2.2 × 10⁻⁴ kgm²; a thermal time constant of 30 minutes is specified for the motor housing. Size 065 and motor length B define the mechanical base body. Balancing follows standard class N stated in the type code. Code N2M denotes digital servo feedback with an integrated multiturn absolute encoder. The centring diameter is 95 mm. A plain output shaft with seal and a side A power connector identify connection version GA0; no holding brake is provided. The standard housing uses natural convection and surface cooling and reaches IP65. Axial motor length is 178 mm. The flange is 100 mm wide and high; the shaft has a diameter of 14 mm and a usable length of 30 mm. Four flange holes, each 9 mm in diameter, and the 95-mm centring seat form the front mechanical interface. Motor weight is 3.9 kg.
